This book was released on 2016-01-01. Dead Zones available in PDF, EPUB and Kindle. Times are tough for shrimpers and fishers in the Gulf of Mexico. The animals they rely on for their livelihood are harder to find. Every summer a dead zone—a region of low oxygen—emerges in the waters along the Gulf Coast. Where oxygen is low, fish and others animals cannot survive. Currently the world has more than 400 identified dead zones, up dramatically from the 49 dead zones identified in the 1960s. The good news is that people can eliminate dead zones by changing agricultural practices and reducing pollution. Using real-world examples, this book looks at the impact of pollution on global water resources, and discusses the interconnectedness of ecosystems and organisms.

This book was released on 2021-01-22. Dead Zones available in PDF, EPUB and Kindle. Dead zones are on the rise... Human activity has caused an increase in uninhabitable, oxygen-poor zones--also known as "dead zones"--in our waters. Oxygen is the third most abundant element in the universe, and it is a necessity for nearly all life on Earth. Yet many rivers, estuaries, coastal waters, and parts of the open ocean lack enough of it. In this book, David L. Kirchman explains the impacts of dead zones and provides an in-depth history of oxygen loss in water. He details the role the agricultural industry plays in water pollution, showcasing how fertilizers contaminate water supplies and kickstart harmful algal blooms in local lakes, reservoirs, and coastal oceans. Algae decomposition requires so much oxygen that levels drop low enough to kill fish, destroy bottom-dwelling biota, reduce biological diversity, and rearrange food webs. We can't undo the damage completely, but we can work together to reduce the size and intensity of dead zones in places like the Gulf of Mexico, Chesapeake Bay, and the Baltic Sea. Not only does Kirchman clearly outline what dead zones mean for humanity, he also supplies ways we can reduce their deadly impact on human and aquatic life. Nutrient pollution in some regions has already begun to decline because of wastewater treatment, buffer zones, cover crops, and precision agriculture. More needs to be done, though, to reduce the harmful impact of existing dead zones and to stop the thousands of new ones from cropping up in our waters. Kirchman provides insight into the ways changing our diet can reduce nutrient pollution while also lowering greenhouse gasses emitted by the agricultural industry. Individuals can do something positive for their health and the world around them. The resulting book allows readers interested in the environment--whether students, policymakers, ecosystem managers, or science buffs--to dive into these deadly zones and discover how they can help mitigate the harmful effects of oxygen-poor waters today.

This book was released on 2016-01-01. The Dead Zone available in PDF, EPUB and Kindle. The #1 New York Times bestseller and “compulsive page-turner” (The Atlanta Journal-Constitution) about a reluctant clairvoyant man who must weigh his options when he suddenly sees the terrible future awaiting mankind—from master storyteller Stephen King. When Johnny Smith was six years old, head trauma caused by a bad ice-skating accident left him with a nasty bruise on his forehead and, from time to time, those hunches…infrequent but accurate snippets of things to come. But it isn’t until Johnny’s a grown man—now having survived a horrifying auto injury that plunged him into a coma lasting four-and-a-half years—that his special abilities really push to the fore. Johnny Smith comes back from the void with an extraordinary gift that becomes his life’s curse…presenting visions of what was and what will be for the innocent and guilty alike. But when he encounters a ruthlessly ambitious and amoral man who promises a terrifying fate for all humanity, Johnny must find a way to prevent a harrowing predestination from becoming reality.

Download and read online ebook Ecological and Practical Applications for Sustainable Agriculture write by Kuldeep Bauddh. This book was released on 2020-06-27. Ecological and Practical Applications for Sustainable Agriculture available in PDF, EPUB and Kindle. Rampant industrialization, urbanization, and population growth have resulted in increased global environmental contamination. The productivity of agricultural soil is drastically deteriorated and requires a high dose of fertilizers to cultivate crops. To ensure food security, farmers are compelled to apply excess chemical fertilizers and insecticides that contaminate soil, air, and water. Heavy loads of chemical fertilizers not only degrade the quality of agricultural land but also pollute water and air. Use of chemical fertilizers also accelerate the release of greenhouse gases like nitrous oxide and methane along with nutrient runoff from the watershed in to lower elevation rivers and lakes, resulting in cultural eutrophication. Farming practices globally in developed, developing, and under-developing countries should utilize and promote sustainable methods through viable combined environmental, social, and economic means that improve rather than harm future generations. This can include use of non-synthetic fertilizers like compost, vermicompost, slow-release fertilizers, farmyard manures, crop rotations that include nitrogen-fixing legumes. Organic fertilizers like compost and vermicompost improve soil properties like texture, porosity, water-holding capacity, organic matter, as well as nutrient availability. The purpose of this book is to document the available alternatives of synthetic fertilizers, their mode of action, efficiency, preparation methodology, practical suggestions for sustainable practices, and needed research focus. The book will cover major disciplines like plant science, environmental science, agricultural science, agricultural biotechnology and microbiology, horticulture, soil science, atmospheric science, agro-forestry, agronomy, and ecology. This book is helpful for farmers, scientists, industrialists, research scholars, masters and graduate students, non-governmental organizations, financial advisers, and policy makers.
